Adurna

At that moment, there was movement in the skies above. 

In order to hide this place from prying eyes, the island had been covered in dense clouds. In fact, it wasn't just the island, but the surrounding tens of miles as well. With a single glance, even someone who wasn't quite informed could tell that these clouds couldn't have possibly formed naturally. It was obvious to Leonel that this was related to someone's ability. 

Thanks to this, the island had been shrouded in a perpetual darkness even though it was midday. Maybe it was in part due to this that the atmosphere from earlier felt so oppressive. 

That said, the clouds served no other purpose aside from concealment. They didn't seem to have any offensive or defensive ability, so when the uninvited guests descended from above in a silver ship, the clouds were completely unable to stop their descent.
